> Get rid of fastMallocGoodSize() and replace it with something generic.

> - fastMallocGoodSize() was Mac-specific and it looks relatively slow and
> non-inlineable. The replacement is based around a single lookup into a small
> table.
> - We now have allocation quantization on all platforms for Vector. I've
> verified that many Vector instantiations are able to recover previously-wasted
> memory as real element capacity. See bug for details.
> - The quantization is also immediately suitable for use with the Partition
> allocator, to avoid fragmentation due to excessive numbers of buckets. To be
> followed up in a future patch series.
